Credited with spearheading the alternative country movement, this Southern rock group emerged from Dallas 20 years ago with a unique sound that blended traditional country melodies with punk rock grit. The tell-it-like-it-is lyric tradition of the band has given its tracks (think: “Let’s Get Drunk And Get It On” and “Intervention”) staying power through the ’90s and into today. Sun 8 p.m.
